The `break` statement is not necessary if it is preceded for example by a `return` statement: switch ($x) { case 1: return 'foo'; break; // This break is not necessary and can be left off. } If you would like to keep this construct to be consistent with other `case` statements, you can safely mark this issue as a false-positive.

This check looks for unreachable code. It uses sophisticated control flow analysis techniques to find statements which will never be executed. Unreachable code is most often the result of `return`, `die` or `exit` statements that have been added for debug purposes. function fx() { try { doSomething(); return true; } catch (\Exception $e) { return false; } return false; } In the above example, the last `return false` will never be executed, because a return statement has already been met in every possible execution path.
